Sorry Rob/Eddy, I can now see that adjustment would have been too much.
It's a fault of mine, Too Much, Too soon. Cheers Bill.

Hi, being a life time sufferer of chronic ducks disease , one off the new rear spring over dampers for my fully sprung twin , hope fully, will help me reach the ground more easily.I received this yesterday.
View attachment 22989
This new D unit uses the same basic components as the already well-proven B/C coilover units. So I am hopeful that testing will be straightforward and quite quick.
It should be a straight fit. Damping and preload are fully adjustable and there is a wide choice of springs. Default is likely to be 300 lb/inch with others available to order. The top mounting is a metalastic bush, the lower mounting is a spherical bearing.
There are no plans to fit a dust cover, although should a customer want to fit one they have sourced, this would be very easy as the spring can be changed without the need for a spring compressor. Looking back at my old notes, it seems very possible the dust cover from the original Armstrong unit may fit. I will try to check this.
QUESTION FOR D OWNERS: With the original unit, does rotation of the pins cause wear in the frame & RFM?
The idea is that the low friction spherical bearing will minimise this possibility, as well as overcoming any possible misalignment.
I discussed with AVO the problem some riders have with the high seat height of the D.
If it is specified at the point of order, during manufacture a "droop restrictor" spacer tube could be fitted internally on the damper rod. No other changes would be required as there is a large range of adjustment of the spring preload. If the coilover extension was reduced so that total travel of the units was the same as on the B/C units, D owners could still enjoy an excellent ride quality with a seat height reduced by about 1 3/4 inches. Although this spacer could be fitted/removed retrospectively, AVO are reluctant to do so, as ideally several components should be replaced when rebuilding units.
Stock items should be available about 3 weeks after prototype testing is completed.
Expressions of firm interest (to me) would be greatly appreciated, as AVO need to decide how many to make in the first batch.
Price is expected to be the same as the existing coilovers, so "£200 +VAT. Carriage UK £10 +VAT. Ireland £15 +VAT Rest of world please email for quote."
Extra springs (one for solo, one for two up touring?) are about £40 each, although experience with the B/C coilovers is that the adjustable preload and damping allows the default spring to cope with a very wide range of loads.
I will have this with me tomorrow at the VMCC Founders Day at Stanford Hall, should anyone want a look. Please visit our COVOC stand and ask for Rob.
